Problems when creating DVD with Scenarist

[leowong1]

Hi, guys, I am making a dvd with structure listed below:

VTS_1
|_______Title_1
|..............|_____Part1-t-pgc
|............................|_____English Subs
|............................|_____Chinese Subs
|_______Title_2
|..............|_____Part2-t-pgc
|............................|_____English Subs
|............................|_____Japanese Subs
|_______Title_3
|..............|_____Part2-t-pgc
|............................|_____English Subs
|............................|_____Japanese Subs

I just wanna ask, is the above DVD structure allowed in DVD specifications?
Or it is just scenarist's problem of not letting me compile the DVD? After a lot of thinking, I chnaged the subtitle name "Japanese" to "Chinese" same as PGC_01 and everything worked well.:) Here I wanna ask, if i really need to create a DVD with the above structure, is there any method using scenarist to do so?

* Here is the Scenarist error log:
Error: The Subpicture Attribute(Language and so on) For Wide in PGC<VTS_01_PGC_02pgc>:Stream<2>:Title<VTS01_Title02> is different from The Reference PGC<VTS_01_PGC_01pgc>
Error: The Subpicture Attribute(Language and so on) For Wide in PGC<VTS_01_PGC_03pgc>:Stream<2>:Title<VTS01_Title03> is different from The Reference PGC<VTS_01_PGC_01pgc>

All PGC's on the same VTS, must have the same aspect ratio ( we can't mix 4:3 and 16:9), and the audio's must have the same bitrate.

Try to create a VTS for every Title.

thanks for your reply, though the thing i wanna ask is that, is it possible that pgc1 has chn and eng sub while pgc2 and pgc3 have jap and eng sub?

[Zeul]

Your problem is the sub assignments. I assume that your video is 16:9 or 4:3 pan-scan. If it is the former then there should be 4 streams in the track. 1 for english wide, 1 for english letter, 1 for chinese wide, 1 for chinese letter. The same if 4:3PS but the streams are wide and pan. (unless you have the subpicture display set to wide & letter / wide & pan)

Next problem is that sub2 is different in title2&3 to title 1. All substreams must be identical across all PGCs/titles in each VTS.

To fix:
You need to make 3 subs for each track. Set stream1 to be english wide, stream2 to be english letter(or only 1 stream set to display wide/letter). Stream2 to be chinese, stream3 to be japanese (with the stream display modes the same as stream1)
You will need to create a dummy sub that can be used for the dummy streams

This will give three tracks each with either 3 or 6 substreams.

Track Result:
Stream#1 english wide -> or it will be combined as wide / letter
Stream#2 english letter -> not needed if as above (wide/letter)

stream#3 chinese wide -> as above
stream#4 chinese letter

stream#5 japanese wide -> as above
stream#6 japanese letter

your scenario:
vts1
----title1
---------english
---------chinese
---------japanese -> this is a dummy stream

----title2
---------english
---------chinese -> this is a dummy stream
---------japanese

----title3
---------english
---------chinese -> this is a dummy stream
---------japanese

How are you selecting the substream? is there a menu or will it be by changing the substream on the remote?

Audio streams follow the same principle - each stream must match across all the tracks in each pgc/title of the VTS. so stream1 could be 5.1, stream2 dts, stream3 2.0. just create a dummy audio clip with besplit that can be used in the dummy audio track.

Hope that helps

or you can just put each title in its own VTS

far better to learn the correct way of authoring instead of a 'workaround'

[leowong1]

thanks a lot, Zeul, thats all i wanna ask. thx for your fast reply.
by the way, my dvdiso is just a r2 anime dvd, so there is no subtitle menu...:)
Actually before you answered my question, i have thought of... can i just compile the dvd with all pgc have chinese and english sub, and then I change the pgc2 and 3 subtitle attribute by ifoedit, in order to solve the problem?

[hendrix]

putting each title in it's own VTS isn't the correct way? - it isn't just a workaround...its a different option, both ways work.

[GM006]

If you're going to put each video in its own VTS you might as well be using DVD Studio Pro. Jumping between VTSs has a bit of a lag time. Some people don't mind it, others do. Either, both will work.

Also to "dodge" the dummy streams, you can set the VTS to only have 2 subpicture tracks per title (instead of all 3). Therefore anyone screwing around in with the subpicture button on the remote will never run into the dummy track.

[leowong1]

gm006 i don't understand what u talk about that dodging dummy subtitles, can u be more specific please? thx

I find that if you have more than one title in a VTS some DVD's players will allow you to skip into the the next Title by using the skip forwards button. I fix this by using a dummy PGC or disabling the UOP but sometimes it can all get a little bit messy. Is using one VTS still the best way to author titles in general though because you don't get so much lag time from a professional authors point of view? I realise each project merits its own solutions.
I also find, and sorry this isn't directly related to this thread, that on certain DVD players that if you press the skip next button quickly you can jump through all the VTS's & titles on the whole DVD which I hate. Is there anyway to fix this? I've noticed it on studio DVD's too so have kind of accepted it.

[mpucoder]

It's funny no one suggested the "right" way according to the specs. It is neither put all the titles in one VTS or put each in its own, but to group titles together with identical audio and subpicture attributes. In this case title 1 would be in one VTS, while titles 2 and 3 together in another. No dummy streams, and no conflicts.

[Crazyjoe]

@ mpucoder

Yeah, it's amazing that people try to use a workaround for a situation which actually doesn't need one. That's the creative DVD Author. :p

@ Cheesus

Yes, some DVD Players will do a jump to the next Title if they can't find another Program within the current PGC or to the next VTS if there's no more Title in the current.

To ommit this you have two possibilities:

1.) Create a dummy track and put it into each PGC as the last program. I normally use a slide show with one black picture and 13 frames duration (the minimum) for this purpose.

or

2.) Go to the last scene of each video and disable the Next Program Search in the Scene UOPs. If you can't find it, it's in the Scene properties window.

[leowong1]

Crazyjoe can u explain why that dummy 13 frames in the end of last pgc can ommit that problem?

[Crazyjoe]

Because this 13 frames program lasts shorter than the avarage user can execute the next program jump on the remote. ;) So before he is able to do so, the post-commandtable of that PGC is executed.

And 13 frames, because that's the minimum length a slideshowpicture can have (at least on a PAL DVD).

Of course it's different if the user continously jumps through the programs, i.e. the player freezes during that time until the user stops at the desired chapter. In that case only my second solution will work effectifly.

[mpucoder]

Actually it's 12 frames, but some authoring programs may require more. For NTSC the minimum is 15 frames. You can also lock out the "next" button with uops for that track preventing the user from skipping the program by holding down the button (some players can auto-repeat).

[leowong1]

thx a lot guys:)

[Cheesus]

thanks too guys.
I do use the UOP to disable next button in the last scene of a feature but I think (& I'll double check this) that if you press the next button quick enough the UOP gets ignored on some stand alone players. I believe it was a Sony player I experienced this with.
Anyone else had this problem?

[Crazyjoe]

Sony Players do have the bad habit to disable all UOPs when they are set codefree. I don't know if you have a codefree player, but it's a possibility.

Some genius must have had this truly brilliant idea... :rolleyes:

[Cheesus]

That clears that up, thanks Crazyjoe. Punishment for having a codefree player, eh? Personally I don't get it, it just makes the DVD look unprofessional.
